To solve this question, the user needs to have knowledge about SOAP, web services, and open-source technologies.
SOAP (Simple Object Access Protocol) is a messaging protocol that allows for the exchange of structured information between different application systems. SOAP is based on XML and is typically used in web services to enable communication between different applications.
Open-source software is software with source code that is available to the public, allowing anyone to use, modify, or distribute the software.
Now, let's go through each option and explain why it is right or wrong:
A. Apache ANT - Apache ANT is a Java-based build tool used for compiling and building software. It is not a SOAP server or client, so this option is incorrect.
B. Apache Tomcat - Apache Tomcat is a web server and servlet container used for hosting Java-based web applications. It is not a SOAP server or client, so this option is incorrect.
C. Jakarta Struts - Jakarta Struts is a framework for building web applications in Java. It is not a SOAP server or client, so this option is incorrect.
D. Apache Axis - Apache Axis is an open-source SOAP server and client framework for building web services in Java. It supports both the SOAP 1.1 and SOAP 1.2 specifications and provides a range of tools and APIs for working with SOAP-based web services. Therefore, the correct answer is:
The Answer is: D. Apache Axis
